Wife of nightclub shooter knew of deadly plans, source says

The wife of the Orlando nightclub shooter knew of her husband's deadly plans and did nothing to stop him, a federal law enforcement source confirmed to Fox News.

FBI agents have interviewed Omar Mateen's wife, Noor Salman, in the days since Sunday's massacre that killed 49 and wounded 53 more. Mateen died in a shootout with police early Sunday morning.

Salman said Mateen shared his plans with her to carry out an attack and Mateen may have even called her from the gay club Pulse during the slaughter, the source said. Salman also confirmed details of Mateen's gun purchases prior to the assault.

A separate source told Fox News that Salman was cooperating with investigators and had shared information about her husband's violent aspirations.
